✦ Synopsis

It is shown that the temperature dependence of the positions and widths of the P( -) and P( t ) bands in the spectra of the reaction center of Rhodopseudomonas viridis can be rationalized in terms of a frequency change of the relative motion of the two bacteriochlorophyll molecules forming a special pair upon the electronic excitation of this pair, and by the dependence of the resonance interaction between these molecules on the nuclear coordinate describing their relative motion.

The CNDO/S method is used to calculate spectra of monomers and pairs in the reaction center of Rhodopseudomonas uirzdis. The special pair is a strongly coupled dimer and its spectrum cannot be described by exciton coupling theory. The S, and S, states are both suggested to be in the long-wavelength

The 3H4~3P o transition in the absorption spectra of Pr 3+ in the hexachloroelpasolites Cs2NaPrxY~\_xCl6 (X=0.1 to x= 1 ) have been measured from 300 to 10 K. The electronic spectra are dominated by electric-dipole allowed vibronic origins enabled by Herzberg-Teller coupling. The two odd parity vibr
